State of Salmon

The Pacific Salmon Foundation’s State of Salmon 2024 Report is a broad-scale evaluation of the state of all six species of Pacific salmon including steelhead found in British Columbia and the Yukon. This report takes a data-driven approach to summarizing the state and trends in abundance for each species of salmon in nine major salmon-bearing regions.

All Regions

Declines in Pacific salmon abundance are widespread, with abundance below the long-term average for most species in most regions. A few hopeful exceptions highlight the resilience of salmon and opportunities for recovery.

How to Interpret this Graph

Each fish above shows the per cent anomaly of current spawner or total abundance over the most recent generation compared to the long-term average (horizontal line) for each region and species. Hover over a fish to see what region it corresponds to or select a species or a region to find out more.

Well-above long-term average. No conservation concern.

Above long-term average. Current outlook is good.

At or near long-term average. Precaution is warranted.

Below long-term average. Current outlook is poor.

Well-below long-term average. Significant conservation concern.

?

Unknown current state due to a lack of readily accessible data. 

Key Findings

1.Declines in Pacific salmon abundance are widespread across British Columbia and the Yukon.

Of the 41 region-species combinations we assessed, more than 70 per cent are below their long-term average spawner abundance.
Salmon species

2.Chum salmon and steelhead are doing the worst with abundances below the long-term average in all regions assessed.

Both species show concerning declines in recent years in all regions. For chum, this mirrors a broader pattern of decline that is occurring across the North Pacific Rim.
Salmon species

3.Northern regions have experienced the most widespread salmon declines.

Most species in these regions (the Yukon, Northern Transboundary, Haida Gwaii, and Central Coast) are below the long-term average in either spawner or total abundance (or both). This finding is concerning given that northern regions are warming faster than the rest of the country.
Salmon species

4.Recent signs of recovery in some regions provide hope for the future of salmon.

For example, coho abundance in the Fraser has increased to above the long-term average for the first time in decades and Chinook spawner abundance in the Fraser and Vancouver Island & Mainland Inlets was above average in recent years. These results provide hope that declines can be stemmed and populations rebuilt if given the opportunity.

Species at a Glance

Salmon species

Chinook

Chinook are below average in northern regions, while Fraser and Vancouver Island & Mainland Inlets have increased above average in recent years.

Salmon species

Chum

Chum salmon have experienced the most precipitous declines of any species with spawner abundance below the long-term average in every region assessed. 

Salmon species

Coho

Coho are below the long-term average in many regions, but in the Nass and Fraser both spawner and total abundances are above average. 

Salmon species

Pink

Pink salmon are doing better than most species with spawner abundance above the long-term average in four out of seven regions assessed. 

Salmon species

Sockeye

Sockeye spawner abundance is above the long-term average in half of all regions assessed.

Salmon species

Steelhead

Steelhead have the lowest absolute abundance of all six species of Pacific salmon, and are below the long-term average for spawner abundance in all regions assessed. 

FACTORS AFFECTING THE STATE OF SALMON

The salmon life cycle extends from freshwater streams and lakes to the North Pacific Ocean, exposing salmon to numerous pressures that can accumulate and interact to influence survival. Over the past 150 years, the number of factors affecting the abundance of Pacific salmon have dramatically increased, challenging salmon survival.

Climate Change

More frequent extremes in temperature, flow, and ocean conditions impact salmon throughout their life cycles. These changes compound and interact with other pressures to affect salmon survival, sometimes unpredictably. Maintaining cold-water refuges and protecting undeveloped watersheds can buffer salmon against climate change in freshwater, but cascading impacts in ocean ecosystems are hindering salmon recovery.+

Salmon species

Fisheries

Although Canada’s commercial fisheries have greatly diminished over the last 30 years, concerns are mounting over the bycatch of non-targeted species and populations in mixed-stock fisheries. Mixed-stock fisheries make it difficult to target enhanced or healthy populations, putting weaker stocks at risk and potentially leading to their over-harvest. Climate change is also making the timing and magnitude of returns less predictable, further challenging sustainable fisheries management. +

Natural Disturbances

Events such as forest fires, floods, and landslides cause ecosystem change and renewal – but the resulting impacts to watersheds can present immediate challenges for salmon. For example, the Big Bar landslide blocked upstream migration of Fraser River salmon in 2019. The debris prevented migrating Fraser salmon from moving beyond the landslide to their spawning grounds, negatively affecting the reproductive cycle of several upper Fraser salmon populations.+

Salmon species

Competition

Although Pacific salmon in Canada are at a fraction of their historical abundance, there are more salmon in the North Pacific Ocean than ever before - and competition for resources can be fierce. Competition among salmon at sea can influence salmon growth, maturity, and productivity, and the impacts are measurable.+

Salmon species

Aquaculture

Open net-pen salmon farms pose several risks to wild salmon, mainly the introduction and transmission of pathogens that can impact wild salmon health and survival. Other potential impacts include environmental contamination from chemical use, pollution from feed and effluent, and direct interactions (predation, competition) between farmed and wild salmon.+

Salmon species

Industrial Development

Activities like forestry, mining, agriculture, and associated infrastructure including pipelines, ports, dams, and railways can have significant impacts on the landscape, altering geomorphology and hydrological processes. Industrial extraction of surface and ground water can reduce stream flows, increase water temperatures, and limit access to habitats.+

Salmon species

Urban Development

Buildings, roads, and coastal modifications like seawalls have led to the loss, degradation, and fragmentation of salmon habitats. With urbanization preceding modern-day record keeping in many regions and the passability of different migration barriers often unknown, the magnitude of this impact on salmon is hard to quantify.+

Salmon species

Hatcheries

Hatchery production can enhance fisheries and provide community connections to salmon, but also poses risks to wild salmon. With five billion hatchery salmon released into the North Pacific annually, competition with wild salmon is a concern. Hatchery salmon can also interbreed or displace wild salmon, reducing genetic diversity, resilience, and adaptive capacity of wild populations.+

Salmon species

Predation

Juvenile salmon are an important food source for many species and naturally incur high mortality from predation. Human and natural disturbances can increase predation by reducing habitat complexity, removing hiding places for juvenile salmon. Piers and docks tend to be avoided by salmon, forcing migrating fish into more open habitats where predators may be waiting, while log booms provide a platform for predators (seals and seal lions) to hunt both juvenile and adult salmon.+

THE PATH FORWARD

This State of Salmon report provides a data-driven assessment of the current state of Pacific salmon throughout their Canadian range. The results suggest that salmon need our help. Conserving and recovering wild salmon in the face of climate change requires forward-looking, coordinated action that is focused on protecting and rebuilding the natural diversity of salmon populations and their habitats. 

 

Indigenous communities are leading the way by revitalizing traditional systems of salmon management and taking legislative actions to protect salmon ecosystems. The Pacific Salmon Foundation is empowering First Nations and other decision makers with data, status assessments, and decision-support tools, collaborating on salmon recovery and resilience planning, and supporting grassroots initiatives through our grant making.
